Abstract:

 Focused on the small sample size problem, a method for face recognition based on local binary pattern features of weight fusing the original and mirror image was
proposed. Firstly the proposed scheme generated the mirror images of the original training samples through the geometric transformation. Then each sample was divided into
several blocks, and the concatenated LBP histogram calculated over each block was used as the face feature of the sample. Next, the original and their mirror images face
feature was merged into new samples by weighted fusion scheme. Finally, the test sample was classified into the correct subject by using the histogram intersection method.
Experimental results showed that the algorithm has achieved a higher recognition rate, with the fact the recognition rate on FERET face database increased by 25.17%, 15.8% and
25.17%, respectively, compared with the contrast algorithm when the number of training sample per subject was 1,2 and 3 respectively. 
